    Hi, I really need help with this as have spent too much money trying to find fault.When driving my zed (300zx twin) It runs fine everthing is normal then out of the blue my car driving accelerator speed will become erratic during driving and my exhaust gauge will climb while doing this to 900+ degrees.can you suggest a fault?

    Its sounding like its leaning out. Try a fpcu bypass and or get a fuel pressure gauge to see if your fp is dropping. Is it only doing it under load/boost? Make sure your vac line has not come off your for. Has this just started to happen.

    no has been ongoing for some time now.Have sent it in for local mechanics to figure out but they have come up with nothing.It happens after driving to my first stop say the shops and when i restart it it starts playing up.Feels like the motor is restricted somehow and when driving normally without booting it,it races past the point im accelerating at with short bursts.
